Construction of bends in mesh cable trays

Bends in mesh cable trays can be made on-site using cutting and bending techniques, allowing for 90° bends, vertical bends, tees, crosses, and offsets without expensive fittings.

Tools and Safety

To create bends safely, you will need: Bolt cutters for cutting tray wires without compromising protective coatings. Hand grinder or file for trimming tray lips when constructing flat bends. Blunt object to flatten tray lips before bending.

Protective gear including gloves and eye protection. Types of Bends and Methods1. Horizontal 90° Bend (Flat Bend)Mark the tray where the bend is required.

Remove a portion of the tray lip (about 2/3 of the tray width) using a grinder or file. Cut down the center line carefully to avoid tray deformation. Flatten the tray lip at the bend point with a blunt object.

Bend the tray to 90° and secure with bolts. Add a gusset piece cut from tray material to reinforce the bend. 2.

Vertical Bends (Up/Down)Cut the upper side wires along the bend line. Bend the tray upward or downward to the desired angle. For tighter radii, leave only one row of wires between cuts.

3. Tee (T-Junction) and Cross BendsRemove intersecting corner blocks from the perpendicular tray section. Align the trays and connect using splice kits or bolts.

Adjust cuts to form radiused corners for smooth cable routing. 4. Offset Bends (Side Shifts)Cut and bend sections to shift the tray laterally.

Ensure the cuts do not compromise structural integrity; use protective caps if needed.

Tips for Professional Results

Avoid cutting all wires completely; leave some connections to maintain tray strength. Work slowly and measure accurately to ensure proper alignment. Use rubber caps or protective coatings on cut ends to prevent cable damage.

Bends can be made live on-site, reducing the need for pre-fabricated fittings and saving cost. By following these steps, you can create custom bends in mesh cable trays efficiently, ensuring safe and professional cable routing for your installation.
